What are the symptoms of chlamydia?

Chlamydia often has no symptoms. When symptoms do happen, they can include abnormal discharge, burning when urinating, pain or swelling in the testicles, or rectal pain, discharge, or bleeding. Symptoms alone cannot confirm chlamydia, so testing is the way to find out.

Possible symptoms

The symptoms depend on where the infection is. Genital or urinary symptoms can include discharge from the vagina or penis and burning when you pee. Some people may notice bleeding between periods. Rectal infection can cause rectal pain, discharge, or bleeding. Many infections remain silent.

Other infections can cause similar signs. A symptom list is a reason to arrange care, not a diagnosis.

What these symptoms cannot tell you

Symptoms cannot confirm chlamydia, identify the body site involved, or replace a test. A clinician needs your symptoms, exposure history, and the appropriate sample to interpret what is going on.

A common misconception

Feeling well does not rule out chlamydia. CDC notes that infection often has no symptoms, which is why testing decisions should be based on exposure, sexual history, and clinical advice rather than symptoms alone.

What to do if you notice symptoms

Ask a healthcare professional for a chlamydia test and tell them where sexual contact occurred so they can choose the right sites to test. If a clinician diagnoses chlamydia, follow the treatment plan and ask when sex can safely resume. Partners may also need evaluation.

Chlamydia is treatable with prescribed antibiotics. Take the medicine exactly as directed and return if symptoms continue or come back. Follow a clinician’s treatment plan rather than choosing antibiotics from a symptom list.

Why testing matters without symptoms

Because asymptomatic infection is common, feeling well does not rule it out. Testing can identify an infection even when symptoms are absent. Ask about screening if you have a new partner, multiple partners, a partner with an STI, or another reason your clinician considers you at increased risk.

When to seek prompt care

See a healthcare provider if you notice these symptoms or if your partner has an STI or symptoms of one. A clinician can check for chlamydia and other causes.
